背景技术
随着社会的持续性发展，无线终端智能化程度也越来越高，人类对终端的依赖程度也越来越高，但是由于终端具有移动性的特点，充电不方便，因此对终端的待机时长要求非常高。
商用的终端多采用增加电池容量等手段来提升终端的待机时间，但是电池容量的增加也就意味着增加终端整体的成本，中低端产品对成本非常敏感。高性能用户设备(High Power User Equipment，HPUE)已经成为热门话题，时分双工(Time Division Duplexing，TDD)迫切需要低插损滤波器来提高发射功率，在相关技术的发射机架构下，要实现较高的功率输出，必须想办法使滤波器、开关等器件插损尽量小。在实际终端使用过程中，在发射信号时都采用相同的发射通路，都要经过滤波器而损失2db左右的功率，导致功耗较高。

具体实施方式
下面结合附图及具体实施例对本申请进行说明。
实施例一
图1为本申请实施例一中发射信号的方法的实现流程示意图，如图1所示，该方法包括以下步骤。
步骤1010：确定信号的发射功率的强度。
在实际应用中，终端与基站建立连接，通过网络与其他终端进行通信，终端可以接收到基站或其他设备发送的信号，也可以向基站或其他设备发送信号，因此，可以根据接收的基站发送的信号确定出终端发送发射信号时的发射功率的强度，比如：确定移动终端的发射功率的强度为22dbm。
需要说明的是，相关技术中有多种确定发射功率的强度的方法，本申请对确定信号的发射功率的强度的方法不做限定。
在一实施例中，所述确定信号的发射功率的强度之前，所述方法还包括：判断当前工作模式是否为时分双工(Time Division Duplexing，TDD)工作模式；所述确定信号的发射功率的强度包括：在所述当前工作模式为TDD工作模式的情况下，确定信号的发射功率的强度。
在检测发射功率的强度之前，需要判断终端当前工作模式是否为TDD工作模式，若当前工作模式为TDD工作模式，则检测发射功率的强度；若当前工作模式为频分双工(Frequency Division Duplexing，FDD)工作模式，则按照FDD工作模式的常规发射通路进行通信。
终端接收基站发送的信号，若接收的TDD信号强且小区注册人数没有饱和时，终端注册在TDD小区，并以TDD工作模式工作。
在实际应用中，判断终端当前工作在TDD工作模式下后，可以根据接收的基站发送的TDD信号强度等与接收信号质量有关的指标，判断终端的发射功率，比如：接收的TDD信号强度为-90dbm，则终端的发射功率的强度可以为9dbm；若接收的TDD信号强度为-100dbm，则终端的发射功率的强度可以为19dbm。
需要说明的是，本申请实施例中的终端的发射功率为终端所发出的信号的功率。
步骤1020：根据所述发射功率的强度，确定所述发射功率的强度对应的通路。
根据检测得到的发射功率的强度，与设定的阈值进行比较，确定发射功率的强度对应的通路，比如：根据发射功率的强度与设定的阈值进行比较得到发射功率为中小功率或大功率，确定发射功率的强度对应的通路为：中小功率对应第一通路，大功率对应第二通路。其中，第一通路和第二通路对移动终端中PA所发射的信号的插损的大小不同。
在一实施例中，所述根据所述发射功率的强度，确定所述发射功率的强度对应的通路，包括：在确定所述发射功率的强度小于或等于设定的阈值的情况下，确定第一通路为所述发射功率的强度对应的通路；所述第一通路包括PA和ASM。
这里，设定的判断策略为设定的阈值，将检测得到的发射功率的强度与设定的阈值进行比较，若发射功率的强度小于或等于设定的阈值，说明信号为中小功率信号，确定第一通路为发射中小功率信号的通路。
第一通路包括PA和ASM，第一通路中不包括滤波器，用于中小功率信号 的通信。

实施例二
本实施例以通路切换开关为单刀双掷开关为例对本申请实施例提供的发射信号的方法进行说明。
相关技术中，TDD发射功率的常规电路如图2所示，包括：PA 201、滤波器(Filter)202、ASM 203和测试座204。其中，滤波器202可以为TDD滤波器。
在实际终端使用过程中，滤波器存在2db的插损，因此，不管发射多大功率的信号都要经过滤波器而损失2db的功率，而滤波器在这里所起的作用就是滤除PA大功率非线性引起的一些带外杂散，但是如果PA在发射中小功率的信号的时候，线性度非常好，信号没有必要经过滤波器进行滤除。
本申请实施例就移动终端在TDD发射中小功率信号条件下，提出一种发射信号的方法，本申请实施例在移动终端发射功率时，在PA线性度比较好的情况下使信号直接跳过滤波器，从而降低PA发射功率，最终达到降低功耗的目的。
本申请实施例提出的发射信号的方法中，TDD发射功率的电路如图3所示，在PA201和Filter202之间设置开关205(即通路切换开关)，相比较图2，只需在发射通路上增加一个开关205，开关205可为单刀双掷开关，开关205作用主要在于：1)在TDD大功率发射情况下，采用通路增加滤波器方式，通过Filter202滤除信号的一些带外杂散；2)在TDD中小功率发射情况下，信号跳过滤波器进行发射。
本申请实施例提供的发射信号的方法的工作流程如图4所示：
步骤4010：判断移动终端是否处于TDD工作模式。
移动终端根据当前信号环境判断是否处于TDD工作模式，响应于移动终端处于TDD工作模式的判断结果，执行步骤4020，响应于移动终端不处于TDD工作模式的判断结果，执行步骤4030。
步骤4020：判断移动终端需要发射的功率。
移动终端根据当前的TDD接收信号强度等与接收信号质量有关的指标判断 移动终端需要发射的功率。
步骤4030：移动终端按照FDD工作模式常规通路发射。
步骤4040：判断移动终端的发射功率强度是否超过预设值范围，响应于移动终端的发射功率强度超过预设值范围的判断结果，执行步骤4050，响应于移动终端的发射功率强度未超过预设值范围的判断结果，执行步骤4060。
步骤4050：经过滤波器发射信号。
通过第二通路进行通信，其中，第二通路由PA、通路切换开关、滤波器和ASM构成。
步骤4060：跳过滤波器发射信号。
通过第一通路进行通信，其中，第一通路由PA、通路切换开关和ASM构成。
本实施例需要移动终端工作在TDD的中小功率发射条件下，通过降低发射通路插损，从而使得输出相同功率下PA的发射功率降低，从而引起功耗下降，提高电池续航能力，提升用户体验。
